Lex Fenwick had joined News Corp’s Dow Jones & Co in February 2012 coming from a long run at Bloomberg Llp. He will be replaced on an interim basis by News Corp COO William Lewis while the company reviews its institutional strategy, according to a News Corp release announcing the shift. Fenwick had overseen Dow Jones’ DJX information service, which has been in beta since its launch last year. “We’re reviewing the institutional strategy of Dow Jones with an eye towards changes that will deliver even more value to its customers. As part of that, we’re planning improvements to DJX,” said News Corp CEO Robert Thomson, who also signaled greater flexibility in Dow Jones’ product offerings is likely in the works soon. Lewis, meanwhile, joined News Corp in 2010 as Group General Manager at News International (now News UK), and was appointed COO at News Corp last year. The one-time Sunday Times and Financial Times journalist will help with the review while the search for permanent replacement is completed.
